Ok I got my C6 from Warehouse123, it is English user manual and VPC-C6EX model.

Here is the problem:

Sometimes when I flip open the lcd, the camera does not focus properly. When I half-press the photo button to focus it tries but always remains blurry. I can take a picture and/or I can record movies but it will always be blurry. Even the autofocus seems to lock onto a target and puts the brackets around it like it is focused but it isnt.

To fix this problem all I have to do us close the lcd, it powers off, then flip it back open and usually it is back to normal fully focused. A few times I have had to do it 2-3 times to get it back to normal.

I have read someone elses post about malfunction after snowboarding with similar problems but he could not even take a photo/movie his was just locked. Mine isnt locked but it is out of focus.

This problem is easily duplicated all I have to do is turn the camera off by closing the LCD and wait a few hours, then flip open the LCD and 90% time it opens up in the blurry mode again.

I'm sorry that you are experiencing this issue, it definitely sounds like there is an issue with the camera. For reference, SANYO does have a (800) number to call and I have included it in this message.

Unfortunately, you have purchased a VPC-C6EX model which is not the USA model, but instead it is a gray market import which lacks a US warranty. So you may want to check on the return policy of Warehouse123 which I suspect is probably not very accommodating.

To others, please purchase from a legitimate authorized reseller. Authorized resellers are listed at www.sanyodigital.com

I have a four year-old C6 that I just love. Have you tried any of the firmware updates that were available a few years ago? Could be a random bootup problem and although it's a longshot perhaps a freshly loaded OS will help. My C6 still gets used occaisionally, mostly I hang it around my neck for motorcycle rides. But I'm itching to look at the new super-slim HD model.

The instructions are similar to the other Xacti models (place .bin firmware in SD card's root; with fully charged battery and while plugged in (powered USB host), power on (cancel USB menu if it appears), set to Playback mode, move the cursor to the Format menu option, hold thumbstick to the left for a few seconds, update firmware, wait until completed).

But CAUTION: An improper firmware update will most likely brick your camera (will no longer work). If you don't understand what you are doing, are simply not sure, would rather not take a risk, do not proceed with the update!

I also had start-up problems. For example the C6 starts taking pictures on its own. On the C5 it was occasional snowy pictures or video. I solved the problem on both cameras by opening them and cleaning the contacts of the main central connector using alcohol and a Q-tip. I guess oxydation builds up after a few years of cold-hot-cold-hot...
When dismantling the camera make sure you pluck the screws onto a drawing you make of the camera's contour on corrugated cardboard; not all screws are the same and they roll away easily.
